android - 构建在 flutter 运行中卡在 "Starting a Gradle Daemon (subsequent builds will be faster)"

Question

这是我使用 Flutter 创建的第一个应用程序。我经常收到这个错误。

安装版本:

PS D:\> flutter doctor
Doctor summary (to see all details, run flutter doctor -v):
[√] Flutter (Channel stable, v1.12.13+hotfix.9, on Microsoft Windows [Version 10.0.18362.720], locale en-US)

[√] Android toolchain - develop for Android devices (Android SDK version 28.0.3)
[√] Android Studio (version 3.0)
[√] VS Code (version 1.43.2)
[√] Connected device (1 available)

• No issues found!

问题是构建卡在了线上

我该如何调试呢？

Answer 1

这根本不是问题。对于您的第一个应用程序，在模拟器上运行它需要相当长的时间。我有一台速度相当快的机器，在模拟器上启动应用程序大约需要 20-22 分钟。
来自 flutter run -v命令你可以看到它有很多东西要下载和设置，因此即使你的互联网速度很好，也要耐心等待。它将被 build 。
另外，不要太担心。在此初始构建之后，后续构建将非常快。
